Hi there,

I got the following error when calling browser.execute("myJavaScriptFunction()");
This only occurs on a deployed version, not in eclipse !

The method is called in

browser.addProgressListener(new ProgressListener() {

@Override
public void completed(ProgressEvent event) {
browser.execute("setData("myJavaScriptFunction()");
}

@Override
public void changed(ProgressEvent event) {}
});

Do you have an idea of the source of the error ??
Thanks,
Emmanuel

Hi,
you run into browser security restriction. Obviously, Eclipse internal
(SWT) browser widget does not respect security restrictions like real
browsers. Without the complete picture/snippet (from where you load the
page and what exactly you want to set) I can't help much.
Best,
Ivan

.... in any case such security error should not lead to application
crash. Could you please open a bugzilla and attach a snippet to
reproduce the error?
Best,
Ivan

Hi Ivan,

The problem occurred only when the URL passed to the browser object was
1. is absolute ("http://server:port/page.html")
2. is build using HttpServletRequest methods (getServerName, etc.)

AND

3. when the HttpServletRequest is stored as an object of my Session class (SingletonUtil.getSessionInstance).

In my previous configuration (only 1. and 2.), it was working properly.

Fortunately, passing only "/page.html" as URL (defined as org.eclipse.equinox.http.registry.resources), solved the problem.

For info, the setData method only pass an argument to a javascript method updating InnerHTML of a div.

Hope that helps to identify the bug.
Cheers,
Emmanuel
